James W Roofing offer an excellent flat roofing service to our customers in Greater Manchester. This includes areas such as Oldham, Rochdale, Stockport and Bury but we are able to travel further afield upon request.


Flat Roofs are perfect for industrial units where you may need to maximise the space above and below the roof, for example in storage units or situations where you may need to walk on the roof. Flat roofs are cost effective and easy to install, but due to them not being able to disperse water quite as well as a slanted roof, they will likely need more roof maintenance work further down the line.

Information About Flat Roofs

Conventional bitumen build up roofing membrane have been used effectively for more than 100 years and are still popular today. With ICO Pal Flat Roofing System, the waterproofing membrane is field fabricated with layers of bitumen, alternating with piles of reinforcing felt. ICO Flat Roof Systems have been known to perform long after their warranty has expired and they are particularly suited when a lot of traffic is anticipated on the roof. They stand up extremely well because of the numbers of layers in the system.

We use solar reflective paint mainly to protect asphalt from the damaging effect of the sun, the silver coating to protect the damage and blistering. The coating should be renewed approximately every 4 years, we recommend that our new flat roofs are all treated with this paint. We would also be pleased to provide costs for replacing coatings to any existing felt roof system.

Types of Flat Roof Systems for installation in Manchester

Roll Asphalt

A roll asphalt roof is made of material that is rolled onto the roof over roof felt and nailed down or applied with cold asphalt cement. It is usually covered with a granular mineral surface, which looks like gravel. The base material can be organic felt or fibreglass felt that is saturated in asphalt. This is the cheapest building material, but it usually doesn't last much beyond 10 years.


Single-ply flat roofs are composed of a single layer of a plastic or rubber-like compound. Some of the more popular materials used today are thermoplastic poly-olefin (TPO) and polyvinyl chloride (PVC), which are both very good at reflecting heat, which saves on cooling costs in the building. Ethylene propylene diene monomer (EPDM) is also popular because it also cools well when white EPDM is used, and it is easy to install. Rubberised asphalt is also used. Single-ply roof systems, depending on the materials, can be self-adhered, applied with hot asphalt or installed by heating the back of the material with a torch. Warranties for single-ply roofs usually are for 10 to 12 years.


Multiple-ply roof systems are also known as built-up roofs (BUR). These are made by overlapping rolls of felt or mats that are alternated with layers of asphalt. This is covered by a granular mineral surface, ballast or tile to protect the layers. These roofs can last 10 to 30 years.

Modified Bitumen

A modified bitumen roof is a multiple-ply roof that is made with modified bituminous membranes, which are made out of a blend of asphalt and a polymer. This allows the asphalt to take on characteristics of the polymer, which is similar to materials used in single-ply roofs. The modified bitumen roof is covered in a mineral or gravel surface, or a liquid coating that provides reflectivity.

Flat-seamed Metal

Flat-seamed metal roofs are made out of small sheets of metal that are soldered together. The sheets are usually designed to look like tile or shingles. The most common metals used for roofs today are copper, lead-coated copper or stainless steel. Metal roofs are light and reflect heat well, but are more expensive.
